Our Services

Architect drawings

We are accredited On Construction Energy Assessors (OCDEA) who can take care of your SAP Calculations from design stage through to ‘as built’ and lodging the EPC.

The design stage assessment is carried out before the building commences, this way we can advise you on the most cost effective way to gain compliance – we will not jump down the route of renewable energy in the first instance, we have many other avenues to explore first.

We will always work with you to achieve a compliant design with no extra charge for revisions. Never will we just tell you “it’s failed”. Full support and guidance is provided as standard throughout the process.
